Abstract: A portable ball launching device is disclosed which includes a support stand positionable on a ground surface and an elongated launching tube mounted to the support stand in a generally horizontal disposition and from which projectiles are ejected. The launching tube has an ingress end and an opposite egress end, and disposed within and concentric with the launching tube is a slidable, linearly reciprocable rod. The rod has an inner end to which a piston is secured for movement concomitant with the rod, and the piston compresses air within the tube in order to forcibly eject projectiles from the egress end. The ball launching device also includes a plurality of interchangeable shooting heads with each shooting head selectively removably securable to the egress end of the tube and each shooting head includes a strip secured to an inner annular gasket which causes deflection of the projectiles as the projectiles are ejected from the launching tube.
